    New MPPT hybrid controller based on genetic algorithms and particle swarm optimization for photovoltaic systems
    (2023) Mammeri, Elhachemi; Ahriche, A.; Necaibia, A.; Bouraiou, A.
    Traditional Maximum Power Point Tracking (MPPT) techniques are unable to reach high performance in photovoltaic (PV) system under partial shading conditions because of the multi-peaks present in the Power-Voltage curve. For that, particle Swarm Optimization (PSO) and genetic algorithms (GA) have been combined in recent years. However, these algorithms demonstrate some drawbacks in tracking accuracy and convergence rates, which impair control performance. In this paper, a new controller based on hybridization of PSO and GA is introduced to track the global maximum power point (GMPP). The proposed algorithm (HPGA) increases the balance rate between exploration and exploitation due to the cascade design of GA and PSO. Thus, the GMPP tracking of both algorithms will be improved. Simulations are carried out based on ISOFOTON-75W PV modules to prove the high performance of the proposed algorithm. From the obtained results, we conclude that HPGA shows fast convergence and very good tracking accuracy of GMPP in PV system even under different shading patterns.

    Robust Controllability and Observability tests of Linear Time-delay Systems with Parametric Uncertainties using Interval Analysis
    (2018) Khelouat, Lila; Ahriche, A.
    In this paper, robust controllability and observability problem of linear time-delay systems with parametric uncertainties is considered. A functional-based transformation is first presented, which transforms the system with delayed measurements into a system without delay formally. Based on the transformed system, we develop an effective method for checking the robust controllability and observability tests of the uncertain system using interval analysis.

    Decentralized overlapping control design with application to rotary drilling system
    (2021) Doghmane, Mohamed Zinelabidine; Kidouche, M.; Ahriche, A.
    The main objective of this paper is the development of overlapping decomposition strategy for con-troller design of rotary drilling systems based on the state feedback technique. The lamped modelof the system has been considered, Graph-based representation has been used to rearrange thestates of the model, and then a new model has been decomposed into subsystems after analyzingthe interconnection terms. The expansion–contraction principle, combined with Lyapunov theory,is used to investigate the global stability of the decomposed system so that controllability of thedesigned controller is guaranteed and its robustness is improved. Moreover, the designed strategyhas been validated with high-frequency mode stick-slip vibrations data measured in an operationalrotary drilling system of an exploration well drilled in an Algerian hydrocarbon field

    Real-time simulation of decoupled power control scheme for wind turbine applications by using RT-LAB package
    (IEEE, 2017) Ahriche, A.; Idir, A.; Boussoufa, A.; Kidouche, M.; Mekhilef, S.
    This paper presents a real time simulation of doubly-fed induction generator (DFIG) control for wind turbine generation system (WTGS). A decoupled power control based algorithm is used to drive the whole system. Where two PI controllers are designed in order handle the active and reactive powers, while a third one is employed to keep a same voltage in the DC-Link. In order to verify the whole algorithm, a real-time simulation is done by means an RT-Lab package which represents a suitable hardware and software for this kind of applications
